Super Street carburetors come with changeable air bleeds. This allows you to calibrate to the finite, your air fuel ratio for more performance and or fuel economy. Quick Fuel Technology is the only manufacture that furnishes changeable air bleeds in this class of carburetor.

CNC machined metering blocks provide more precise fuel metering and control, improved throttle response and a uniform fuel performance curve. Machined from premium billet aluminum to the strictest tolerances and then anodized for protection and good looks, these blocks are the standard by which performance carburetors are measured.

The aluminum fuel bowls feature several high performance innovations, including repositioned fuel bowl screws for 40% more thread engagement and internal baffles that stabilize the float level. Dual sight glass windows facilitate setting the fuel level. Each bowl is equipped with dual fuel inlets and includes an inlet fitting.

Slabbed Teflon coated throttle shafts are assembled with Teflon ribbon bearings. Stainless steel throttle plates are attached using low profile button head screws which result in maximum air flow with minimal throttle effort. Most carburetors and all service throttle bodies come with an adjustable secondary cam bracket which allows the user to adjust the secondary air flow by simply turning a screw.

Super Street Series are offered with a fully adjustable electric choke. Simple one wire hookup combined with easy adjustability make for a trouble free choke setup.

Non-stick gaskets.

The standard by which all other power valves are measured Quick Fuel Technology exclusive in-house design has become the power valve of preference by professional race teams in virtually every circuit where carburetors are used. Not only does the Four Door power valve have a much greater flow capacity, but a quicker response rate and tighter limit bands allow engine builders to precisely tune the power enrichment phase of their calibration. Each Four Door power valve is hand tested and set to the stamped value. The thicker molded diaphragm adds increased protection against backfire induced rupture and corrosive fuels.

Dual vacuum ports are found on all Street Series Carburetors. The outside one is for manifold vacuum, and the inside is for ported spark advance signal.

All Street Series carburetors have a Pollution Control Valve (PCV) port mounted in the throttle plate, drawing equal vacuum from two venturi's, not just one - perfect for street driven machines that need a PCV or power brake vacuum hook-up.
